SPECIFICATION forming part of Letters Patent No. 768,340, dated August 23, 1904.

Application filed September 21, 1903. Serial No. 174,078. (ModeL) To all whom, it may concern.-

Be it known that 1, WILLIAM ORMSBEE,

- J r., a citizen of the United States, residing at Kaukauna, in the county of Outagannie'and State of Wisconsin, have lnvented a new and useful Envelop, of which the followingis a.

specification.

' This invention relates to an improved envelop, particularly designed for use as a payenvelop, and has for its object to provide a simple, inexpensive, and efficient device of this character adapted to automatically open when pressure is applied to the side walls thereof, so as to facilitate the introduction and removal of thecontents of the same.

Afurther object .of the invention is to form the envelop with longitudinally disposed creases or fol'ds extending parallel with the side walls thereof, so that when pressure is applied laterally to the envelop the mouth thereof will expand, and be held in the distended position and when the pressure is removed cause the envelop to assume its normal in accordance with my invention. Fig. 2 is a similar view showing the envelop compressed and the mouth thereof distended.

Fig. 3 is a transverse sectional view of Fig. 2.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates the envelop of the usual form and construction, preferably rectangular in' shape, as shown, and formed of paper, linen, or other suitable material. The front wall 2 is preferably extended to form an end flap 3, adapted to close the mouth of the envelop, said flap being gummed in the process of man- I ufacture or left ungummed, as desired. The front and rear walls 2 and 4: are formed with longitudinally-disposed folds or creases 5, extendingp'arallel with the side edges-f the envelop and spaced a short distance there from to form side sections, as shown, said folds or crease being formed in the envelop either before or after the blank is folded. The creases or folds '5 preferably extend the entire length of the envelop, including the flap to the side walls thereof the edges 6 will be forced inwardly, spacing the front and rear walls of the envelop and permitting the ready introduction or removal of the contents thereof, as clearly shown in Fig. 2 of the drawings.

the thumb and fingers and compressed edgewise, which expands the mouth of the envelop and automatically raises the flap 3, thereby permitting the bank-notes, bills, or other papers to be readily insertedtherein, after whichthe' envelop may be sealed in the ordin'ary manner by pasting or otherwise affixing the end flap to the front wall of the envelop.

By having the creases formed in the end flap, as well as the body of the envelop, it permits the mouth of the envelop to present a substantially rectangular opening when the side walls are compressed without tearing or otherwise injuring the flap or envelop.

I-claim, and desire to secure by Letters Patent, isv 1. An envelop having its front andrear walls and closing-flap longitudinally scored to permit said walls to expand and thereby automatically raise the closing-flap when the'longitudinal edges of the envelop are compressed laterally. 1

2. An envelop having its front and rear walls longitudinally scored, one of said walls being extended to form a closing-flap similarly scored to thereby permit the flap to automatically raise and present a substantially rectangular and unobstructed opening at the mouth of the envelop when the longitudinal edges of the envelop are compressed laterally.

3. An envelop having its front and-roar walls In practice, the envelop is grasped between 3, so that when pressure is applied laterally Having thus described the invention, what scored longitudinally on lines parallel With my own I have hereto afiixed my signature in the edges of the finvelop and forming?"1 (side the presence of two witnesses. sections, one of t e Wa ls being eXten e to form a closing-flap adapted to automatically WILLIAM ORMSBPBJ 5 raise When pressure is applied laterally to the Witnesses:
